Description

Multi-way disposable valve and multi-way valve that can be operated with gas capsules Removal device for emptying pressure vessels.

Two of the invention is an inexpensive disposable valve with a uder to create two ways for pressurized can and beverage container, with optional arrangement an axial or eccentric riser pipe, which in conjunction with a special simple and inexpensive dispensing or spraying device, the introduction of pressurized gas with simultaneous product removal from a container that is 100% full with product allowed.

Such a device would be used for a) aerosol industry b) beverage industry be of great interest.

To a) There is an extraordinary need in the aerosol industry that To reduce the currently high packaging costs for aerosol products achieves that instead of the normal filling method - 50% product, 25% liquid gas, 25% Empty space - the aerosol can is 100 filled with product without the addition of propellant gas and emptying by means of a special pressurized gas Spray head takes place.

Regarding b) In the brewing industry, meth-ds are sought in order to find particularly inexpensive ones A-u. Reusable beverage packs to create larger volumes to accommodate the changing Consumption habits have to be taken into account. For this reason, a party box was created with a volume of 4 liters and an aluminum party keg with a volume of 5 liters are to be emptied by means of complex tapping devices (spear) developed the new KEG systems in England, which are permanently closed with a = equipped with a valve.

This system requires extraordinary capital investment when used the existing barrels and filling and cleaning systems cannot be used.

A system must therefore be created that has the advantages of the KEG system transfers to existing beverage packaging.

This is achieved by using a two-way valve, preferably Diaphragm valve, in connection with a perforated disc and in cooperation with a special Zapftu.Sprüh -vorrichtung are designed so that the desired tasks be achieved.

Figs. 1-5 show a diaphragm valve consisting of three parts.

In Fig. 1, a Kromer screw (1) is used for the brewing industry Drum closure with hole washer seal (2) and membrane (3) with valve cone arrangement (4) shown.

The perforated sealing disk (2) encompasses the Kromer screw (1) like a cap and engages in a circumferential collar (5), on the underside of the Kromer screw (1) with undercut, while the membrane (3) again engages under tension in an annular groove (6) extending around the entire circumference of the seal = perforated disc (2), and in connection with perforated washers = gasket (2) covers the entire container opening.

Instead of an eccentrically arranged riser pipe (7) Fig. 13 an axial riser pipe (7) is used. The special design of the valve cone (4) on the diaphragm (3) allows the arrangement of a second path in the valve cone (4) for the subsequent introduction of pressurized gas by means of an extraction device Valve cone (4) has on its upper and lower side, arranged axially, two vertically separate cup-like depressions (8,9), which are divided into radial Openings open and each cause a connection to the inside of the container, which is separate from each other gas u. liquid-tight thanks to valve cone seat and circumferential hose seal (10) are locked.

The gas paths (8) are offset in the cone (4) to the fluid paths (9) arranged and are located in the walls forming the liquid paths.

This valve cone arrangement advantageously allows any Riser pipe cross-sections. The desired cross-sections are indicated by diagonal or At right angles to each other bores in the valve cone (Fig. 1-5) are reached.

Fig. 2 - 5 shows embodiments of membrane valves, which by means of Sheet metal valve plate (11) can be crimped onto the rolled edge of a can.

Fig. 9 shows a tapping device (12), which by means of a bayonet lock (13) is fastened in Kromer screw (1). The opening element (14), by means of screw, bayonet = Closure or lever arranged vertically movable with it at its lower end a non-return valve (15) on which a beverage backstop (16) on = The diaphragm (3) is opened by lowering the opening element with valve cone (4) lifted from the sealing seat (59) of the valve opening, while at the same time the valve pipe (15) is raised so that fluid is removed via path (9) and the pressure gas is reduced is introduced through the reducing valve (17) via path (8). is lifted by gas pressure and prevents gas = backflow from the inside of the can. Beverage backstop (16) prevents the dispensing tube from running empty when the dispensing device (12) is detached (9) in the dispensing device (12).

Fig. 10 shows a tapping device (12) for commercial purposes for connection to C02 bombs by means of a hose connection and C02 fittings, in the tap position with open valves.

The dispensing device (72) is attached by means of a bayonet lock (13) One-hand operation on the container lock (1) attached. For liquid-tight attachment the dispensing device (13) and for opening all valves in the container closure (1) and in the dispensing device (12), becomes the by turning motion to Overcoming pitch used in the thread. About 35% of the pitch are used for liquid-tight Attachment of the dispensing device to the container closure, while the remaining approx.

65% to press the diaphragm valve from the valve opening and can be used to lift the opening element (14) from the gas-tight seat (18) (14) in the dispensing device (12) is axially movable and liquid-tight Compression spring (19) above half of the sealing plate (20) of the opening member (14) causes Press fit on the rubber seal (18) and thus gas-tight closure of the gas path; tnd at the same time tight = fit of the beverage return lock (16) when the dispensing device is removed The container closes at the same time as a result of pressure relief and pre-tensioning the membrane of the valve cone (4) the valve opening in the container closure. On the valve cone (4) an adapter tube (21) is preferably arranged in order to achieve a shorter design of the To achieve adapter (22) on the opening member (14) so that it is in the housing of the tapping device Is housed in a shock-proof manner.

Fig. 6 with top view Fig. 8 show spray head (23) with attachable C02 capsule for aerosol containers, which are closed by means of two-way valves, used into a valve, which is shown in partial section, by pressing the spray head (23) the adapter (22) of the spray head lies gas-tight in the cup-like recess (8) of the valve cone (4), lifts it from its seat, while at the same time the valve tube (15) is lifted from its sealing seat so that compressed gas is reduced by the reducing valve (17X via gas path (8) while lifting the hose seal (10) with the liquid The liquid is supplied via the riser pipe (7) and the liquid path (9) in the valve cone to the channel (24) of the spray head under pressure to the spray nozzle (51) promoted.

In Fig. 6 and>, in order to achieve the smallest possible structural dimensions, exemplary embodiments of reducing valves (17) depicted, which insist on feathers Fig. 7 is a reducing valve using a membrane (25) with a piston pin (26) and bores (28) shown, which is introduced gas-tight in the housing (29) Diaphragm (25) with piston pin (26) with different but coordinated Surfaces act as pressure pistons against each other. The high gas pressure (50atü) from the The CO2 capsule acts on the piston pin (26) and lifts the sealing cone (30) from the gas line (8) The gas pressure exits through the hole (28) in the membrane piston (25) on the underside from, the gas-tight with a slight bias with its outer edge (32) in the housing (29) is clamped. If pressure has built up below the clamped diaphragm (25), the in relation to the piston = surface pressure of the piston pin (26) is raised the membrane with the piston pin and presses the sealing cone (30) gas-tight into the gas duct (8) .- If the seal (33) on the piston pin leaks, the The function of the reducing valve was canceled because the high gas pressure was also applied to the large one Surface of the clamped membrane acts, causing an impermissible pressure build-up in the container An optional bore (34) is provided, the atmospheric one Connection and a cone (35) arranged on the lower diaphragm piston surface is gas-tight on the gas opening (8) below it to the can, so that a Gas extraction from the spray pre-weighting is no longer possible.

11 and 12 show exemplary embodiments of a further very advantageous one And inexpensive valve design.

While in the embodiments 1-5 a container = closure For barrels made from Kromer-Sohraube (1) Perforated sealing disc (2), soft-elastic membrane (3), hard elastic Sohlauchdi.htung (10) and for aerosol cans from valve plate (11) Metal perforated disc (2), flexible Membrane (3), hard-elastic Hose seal (10) exist, takes over the membrane in these execution examples (3) also the function of the sealing hole = washer, while the perforated washer the function of the valve plate takes over. In the exemplary embodiment (13) the membrane takes over at the same time the function of the perforated sealing washer, while the Kromer screw remains unchanged This is achieved by choosing the material (plastics used) , according to the function to be assumed, instead of hard-elastic Plastics for the membrane are now soft elastic plastics that only The lower restoring force for flexible ones is used Due to the special design of the membrane, plastics are used with greater wall thicknesses and achieved by assigning stiffening ribs on the underside of the membrane.

11 and 12, a valve closure is shown which consists of consists of a hard-elastic perforated disc (2) which covers the entire container opening (37) by a press fit (38) on the rolled edge of the can (37) inside and outside (2) is on its, the inside of the container facing part with a circumferential groove ring (39) which is supported on the inside of the container opening (37) hard elastic perforated disc (2) cannot seal the hard container opening take over.

For this reason, the membrane (3) is made of soft elastic plastic With its outer edge (4o) it engages in the U-ring (39) with two Undercuts of the perforated disk and covers the press fit (38 of the perforated disk with soft elastic plastic, so that a gas- and liquid-tight closure is caused by a press fit on the rolled edge of the container opening soft elastic membrane is thereby achieved that its edge (40) into the groove rings (39) of the perforated disc (2) engages and that the wall thickness of the circumferential U-ring (41) is so strong that it is in angled lever-like spreading of the U-ring enables the diaphragm valve cone to be lifted off, for reinforcement of the membrane (3), the underside of the membrane is provided with stiffening ribs (43) to bring about a higher restoring force, the spread U-ring acting as a tension spring and the ribs (43) act like a compression spring.

The valve opening (47) of the hard-elastic perforated disc (2) is accordingly of the extraction devices to be used with screw thread (24) or with sealing lips (25). With correspondingly thinner sealing lips = formation, hard-elastic Synthetic the desired elasticity and thus sealing effect around the spray head shaft achieved.

Fig. 13 shows a Kromer barrel closure (7) for the beverage industry, but to accommodate a flexible membrane (2) with molded seal (48) which covers the Kromer screw like a cap. The Kromer screw (1) or a cylindrical screw with a circumferential groove ring on the underside (46) into which the circumferential groove ring (40) of the membrane is supported by the The valve cone (4) engages in the opening of the Kromer-Sohraube under pretension.

In Figs. 14 and 15, diaphragm valve (3) is made of flexible plastic in connection with a valve plate (11) made of metal as an exemplary embodiment, with axial and eccentric riser pipe design shown. The membrane covers the entire valve disk and the container opening and encloses the one in Fig. 14 The U-ring arranged in the valve element is supported on it, while in Fig. 15 the inwardly drawn grooved ring in the valve disk to define the outer edge the flexible membrane is made by crimping, with simultaneous support on the inside wall of the can provide a better sealing effect with a lybyrinth seal, the when the valve disc is attached to the rolled edge, it is gas- and liquid-tight in press fit.

One or more sealing rings and an adapter pin are optionally available on the sealing cone (52) arranged.

Fig. 16 shows the sealing of a spray head on the valve opening is caused by the fact that the spray head lip-like (53) the sheet metal opening from the inside and covered outside in the sliding fit.
